Why do AI video clips drift in color at all?

Every export, re-encode, and image round-trip nudges color. Generators decode a seed frame, render in their own color space, then re-encode to 8-bit yuv420p for delivery — and each conversion clips and rounds values slightly. Chain several clips and those small shifts accumulate into visible mismatches in brightness, contrast, and hue.

Is color-recovery export different from just screenshotting the frame?

Yes. A screenshot or plain export preserves the already-shifted delivered values. Color-Recovery actively pre-compensates for the encoding round-trip so the frame you feed the generator is closer to the true color.

Export a last frame without color shift

The “last frame → next start frame” workflow is how almost everyone extends AI video — but a naively exported frame already carries encoding drift before the generator even touches it.

What you're seeing

Your seeded clip starts a step off-color from the clip it continues
Drift that seems to begin at the very first frame of each extension
A grade that won’t hold no matter how carefully you prompt

Why it happens

When you grab a frame from a delivered 8-bit yuv420p video, it has already been chroma-subsampled and rounded. Feed that frame back in as a seed and the generator builds on an already-shifted starting point, so drift is baked in from frame one.

How to fix it with Color Correct

In Color Correct, open the source video and locate the frame you want to export.
Export it using Color-Recovery, which pre-compensates for the encoding round-trip.
Use that recovered frame as the start frame for your next generation.
After generating, frame-pair match the new clip back to the reference to clean up any residual drift.

Recommended settings

Color-Recovery offers drift-correction levels — start at the default and increase if your generator round-trips aggressively.

Free plan available — watermarked outputs, no card required.
